Abstract

The invention discloses a rubber cushion block for steel roll support and a preparation method thereof, belonging to the technical field of steel roll support spare parts. The rubber block for steel roller support of the present invention is made of the following raw materials in parts by mass: styrene-butadiene rubber: 100 parts; carbon black: 90-115 parts; rubber powder: 80-105 parts; calcium carbonate: 35-50 parts Clay: 70-80; Aromatic oil: 40-50 parts; Accelerator D: 1-2 parts; Accelerator DM: 1-1.5 parts; Sulfur 12-20 parts. In the preparation method of the present invention, the rubber cushion blocks for steel roller support are prepared through the steps of master batch rubber mixing→second stage mixing→master batch rubber kneading machine vulcanization→molding vulcanization. The rubber cushion block for steel roll support of the present invention has the advantages of low production cost, high processing efficiency, light volume, convenient use and operation, no damage to the surface of the steel roll, and long service life.

Description

technical field [0001] The invention relates to the technical field of steel roller support spare parts, in particular to a rubber pad for steel roller support and a preparation method thereof. Background technique [0002] The iron and steel industry is one of the basic industries of my country's national economy. With the vigorous development of the domestic iron and steel industry, the iron and steel industry has shown a rapid growth momentum. Industries that mainly consume steel such as construction, machinery, automobiles, real estate and other industries have strongly stimulated the growth of steel demand. [0003] Typically, steel rolls are used to roll metal billets to form various metal products (eg, various steel shapes). Steel roll racks are used to store or stack steel rolls. At present, steel rolls are usually stacked in direct contact with steel rolls on the steel roll stand, which can easily lead to mutual abrasion or contusion between the roll surfaces of t...
